Answer:
27.25°C
Explanation:
hello,
this question involves heat transfer in an object and to find the final temperature, we'll use formula for heat transfer
data;
mass = 12g
heat energy (Q) = 12J
initial temperature (T1) = 25°C
final temperature (T2) = x
specific heat capacity (c) = 0.444J/g°C
heat energy(Q) = mcΔt
Q = mc(T2 - T1)
the final temperature was 27.25°C
Mass of AlCl₃ : 93.39 g
<h3>Further explanation</h3>Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M
the volume of the solution = 330 cm³=0.33 dm³
the concentration of the solution = 283 g/dm³
mass of AlCl₃ :
